What does --eraseAll do in odacli delete-database

I am running ODA 19.13 on x8-2s single node database. I would like to delete a database and all related files while leaving other databases intact. I ran the following help command to look at options for deleting a database and am curious what --eraseAll does and if the default is to remove all files related to the database. The weird thing is the "X8-2 Deployment and User’s Guide" mentions nothing about this option.
